buoyancy force is the force that helps one to float.
it is expressed as = (density of medium) × (volume of body)×(acceleration due to gravity)
which means the higher the density of water Sanjay swims in the easier it is for him to float.
The beaches of Mumbai have saline water which means they have salt in them and have higher density making Sanjay's swim easier by making him float
while the river water is less dense and this is what makes it hard to float in it and swim
